Rogers DiClad 870 PCB With 1oz Copper and Immersion Gold For WiFi Antenna

We are excited to introduce DiClad 870 laminates, an advanced addition to our product range that aims to push the boundaries of PCB substrate technology. With a focus on innovation and performance, these PTFE-based composites with woven fiberglass reinforcement offer several notable features, while also addressing certain limitations associated with traditional laminates. Let's explore the unique qualities of DiClad 870 and gain insights into its potential shortcomings.

DiClad 870 Introduction:

• DiClad 870 laminates represent a significant departure from conventional laminates in terms of composition and performance. By utilizing fewer plies of woven fiberglass and increasing the ratio of PTFE content, these laminates achieve lower dielectric constants (Dk) and dissipation factors compared to other laminates in the DiClad series. However, it is important to consider potential trade-offs when evaluating their suitability for specific applications.

Enhanced Features:

• Reduced Dielectric Constant: DiClad 870 exhibits a dielectric constant of 2.33 at 10 GHz and 1 MHz, 50% RH, enabling improved signal integrity and reduced signal loss.
• Lower Dissipation Factor: With a dissipation factor of 0.0013 at 10 GHz and 0.0009 at 1 MHz, 50% RH, DiClad 870 offers lower energy dissipation, resulting in enhanced electrical performance.
• Temperature Stability: The temperature coefficient of DK (TcDK) of -161 ppm/°C between -10°C and 140°C at 10 GHz ensures stable performance across varying thermal conditions.
• Dimensional Stability: DiClad 870 exhibits excellent dimensional stability, ensuring precise manufacturing processes and reliable PCB assembly.
• Uniform Electrical Properties: The laminates provide highly uniform electrical properties across different frequencies, guaranteeing consistent performance throughout the frequency spectrum.
• Mechanical Durability: DiClad 870 maintains consistent mechanical performance, ensuring long-term reliability and resistance to environmental stressors.
• Chemical Resistance: Offering excellent resistance to chemicals, the laminates can withstand harsh operating conditions, enhancing the lifespan of electronic systems.
• Moisture Absorption: DiClad 870 boasts the lowest moisture absorption rate among PTFE-based composites, minimizing the impact of moisture on performance.

Addressing Limitations:

• While DiClad 870 exhibits remarkable features, it is crucial to acknowledge certain limitations that may affect its suitability for specific applications:
• Limited Frequency Range: The stable dielectric constant (DK) over a wide frequency range is a notable advantage. However, at extremely high frequencies, DiClad 870 may not provide the same level of performance as specialized laminates designed for those frequencies.
• Narrow Line Width Constraints: Although the lower dielectric constant supports wider line widths for reduced insertion loss, it may also impose constraints on designs that require narrower line widths for high-density circuitry.
• Higher Material Cost: The advanced composition and performance of DiClad 870 laminates may result in higher material costs compared to conventional laminates. This factor needs to be considered in cost-sensitive projects.

DiClad 870 laminates introduce exciting advancements in PCB substrate technology, offering enhanced features and addressing certain limitations associated with traditional laminates. Their lower dielectric constants, improved dimensional stability, and reliable performance make them a compelling choice for a range of applications. However, it is essential to carefully evaluate the specific requirements of each project, considering factors such as frequency range, line width constraints, and cost considerations. DiClad 870 laminates can undoubtedly unlock new possibilities in high-performance PCB designs, but informed decision-making is crucial to maximize their benefits in your unique applications.
